GDR3 battery life improvement (or a bug?)

Battery life has definitely been increased on my Lumia 720. Its been 2 Days and only 50 % battery life is over. Typically i keep my 2G connection on during the day and switch off during the night. Really happy with GDR3 Update. :)

My L920 don't get battery back up as u get.. Bt plz tel me how is the vibration ... In my phone its seems to very low effect can't sense it ! Its totally dump

About my Lumia 920, vibration is OK, but it has never been very strong one and It is just on the beginning - so you can make a short ring tone to make vibration exist more (then it work as a vibration - a short ringtone - a vibration - a short ringtone, etc.)

Someone out there who experience worse battery performance with the 8x since gdr3(dev. Preview) and/or official release with HTC firmware? Before all this it was acceptable after gdr2. But now it's back to after portico update.

Standby its about 4% with only battery sense, whatsapp and Bing weather. In use it goes to up 15% and draining fast. Even though it's some light use. Average lifetime is about 15 hours

So as somebody who claimed to have worse battery life with GDR3 on his 928 I have found out why...

Somehow I managed to enable the "Use cellular data for limited Wi-Fi connectivity" option. Ever since I disabled that, battery life has been ridiculously incredible! Typical use would leave me dead by the time school ended (7am-4pm) but now I can go all day in school plus work (now 7am-10pm) with 40% battery life when I get home! It's awesome!

Initially had some issues with my battery life but resolved (email was constantly syncing, removed account and added anew) and I'm now finding it difficult to discharge my battery (Lumia 920). I'm at 74% after about 10 hours (from 100%) with 3G constantly on, glance screen and double tap to wake. Emails syncing every 15mins! This is great!
